in section, of a tank-car constructed in acu e n l cordance with myinvention. Fig. 2 1s an end elevation with r a portion of the tankbrokenaway. Fig. 3 is a sectional view taken on the lineS 3 of Fig. l. Fig. 4isa plan view of the body-bolsterl and draft-sill.A

F 1g. .5 is a sectional-view taken on the line 5 5 of Fig. 4. Fig. 6 1sa sectional view on the line 6 6 of Fig. 4. Fig. 7 illustrates a modi'fied form of body-,bolster and draft-sill. Figs ,8, 9,10, and 1lillustrate modied forms of a tank-brace.

This invention relates to a new and useful improvement in tank-cars, theobjectbeing to provide a strong and simple tank-car at a ver." low cost.l'

I1 a car constructed in accordance with my V@vention center sills underthe tank are replaced by a longitudinal tank-brace constituting aninteriorly-arranged sill. This tank-brace receives the bu'liingandpulling stresses and stiiliens the tank structure to such an extent thatexterior center sills ar.

ranged between and directlyvconnected to the body-bolsters areunnecessary.

Referring to the accompanying drawings, telescopically-arranged sheetsform the top and sides of the tank, the lower edges of said sheetsbeing,r secured to a bottom sheet 1, which preferably extends from endto end of the tank. Heads 2 are riveted to the ends of the tank. 3indicates the usual filling-deine.`

The tank may be made of circumferentiallyarranged sheets, if desired.

A running-board t surrounds the tank and secured to brackets 5, whichare riveted to the tank. The running-board brackets are sometimessubjected to shocks in service, whicli in the constructions employedprior to my invention would loosen or tear out the thereby causinleakage. In accordance'with Inv invention these brackets' are made offranrible material, preferably chilled cast-iron. n a

construction of this character the rivets which secure the brackets tothe tank are' protected from violent shocks, as the bgrackets will breakwhen subjected to a shock that would injure said rivets.

Hand-rails 6 are secured abler distance above the running-board.

Short draft-sills are riveted to the under .side of 'the tank. Thesedraft-sills are preferably formed of pressed metal comprising a curvedtop portion 7, depending webs 8, and

to the tank a suitl bottom iianges 9. Draft-lugs 10 are secured to theWebs 8. Any suitable draft-rigging may be arranged between thesedraft-lu s.

In the drawings' have omitted the draitl i riggin and draw-bar, parto mresent invention.'

Buffer-bild draft-sills and' areprovided With suitable recessesto'receive t e draw-bar.

cke cover the outer ends of the y as the same form no Flan es 11 -areformed integral with the buiferlocks and conform to the shape of the.draftsi1ls1 These flanges rest on the ldraftesills and are securedthereto by means of bolts12, which 'also support; a draw-bar-carrieriron 13. The buffer-blocks are vreinforced by rigid pressedmetal members14', which vare riveted to the inside of the draft-sills.

In' the referred form of my invention the, f

innere s, of the draftfsills aresecured to body-holsters 15 by means ofrivets or bolts. Y

Thesebody-bolsters may be cast or made of pressed or rolled shapes; asdesired.v

Fig. 7 illustrates a the draftsill 7a and body-bolster- 15 are eastintegral.

nfo'diication in which The body-holsters -are provided l' with a curvedtop portion which conforms to l lthe shape of the. tank and is rivetedthereto.

Extensions, which comprise a curved top portion 16v and reinforcing-webs17, are formed integral with the body-bolsters and secured to thetank bymeans of riyet-s 18 and 18, the'rivets 18a passing through a tank-brace19, located inside oi the tank.

The tank-brace 19, which. is of approximately the same length-as thetank, `is cornposed 'of two plates arranged in theform of an inverted Vriveted together at-the top and provided with iianges at the bottom,vwhich are riveted to the bottom of the tank. A

suitable opening is formed in the top of this IOO- IOS

ni'itted to the, tank-brace 19 from the draitand `principle of my sillsand body-holsters Without exposing the tank structure to injuriousshocks.

The tank-car herein shownimay b ecomL pared to a beam supportedy at itsends, the .weight of the tank and its'contents actingl as a i rceapplietll'betwecn*the supports. This 'torce is vresistetl-`loy abox-.girder construction, Iin whichthc bottom tank-sheet 1 and the lower`i'iortidn of the tank-brace 19 form the tensiorie-,leriient anid thetop portion et' the lbrace 19, thef'compression clement.

The ,design of the ried 1n. m. ny `Ways.

tank-ln'ace 'may be va- For example, vthe shape illustrate in Fig. 3could be 'formed of a single sheet of metal 19, as shown in l? 8.

in Fig 9 two channels lylll) are spaced apart i and riveted to the tank.Connecting-bars 22 are riveted to the top of these channels.

Fig.l 1(). illustrates a tank-brace cjomposed of a U-sliaped meinher18), rivetel'l to the bottom of the tank aiull provided with acover-plate T23. flierclthis construction used, ,thebottom tank-,sheetcould be made of lighter material, as tl rc `U-shaped member and itscoverplate form a complete boxgirder. l, v i

` The tank-brace shown in Fig. 11 is composed ott an inverted-U-Qslrapcdmember 19, provided with flanges at the bottom, which are riveted to thetank. l I

I am laware that minor changes in the eonstruction, arrangement', andcombination of the several )art-s of my device can be made and sub'stitted for thoseherein shown and described Without departing from the natire invention.
